Medical prodigy Lin Qingyue is reborn as a doomed supporting villainess in a period novel and bound to the sharp-tongued System 007. Amid the chaos of multiple dimensions merging, she must overturn her seemingly certain death. Cloaked in the guise of a gentle, miraculous healer, she plots from behind the scenes and navigates the competing forces around her.
Gu Linyuan, a villain from the cultivation world, has had fragments of his shattered soul scattered across the modern city. He develops a sick obsession with this black-hearted woman, who wields silver needles and schemes with equal skill. The original heroine, Su Qingyin, has long since been replaced by a quick transmigration runaway who holds a strategy System and is determined to steal her fortune. Meanwhile, Lu Zhixing of the Special Investigations Division keeps a close watch on anomalies between worlds. His cold gun barrel is sometimes aimed at visitors from other timelines, and sometimes clears a path to survival for her.
As the period novel, cultivation world, and modern city collide and merge across fractured timelines, Lin Qingyue turns silver needles into blades and fights her way through the deadly crossfire between false and true heroines, an obsessive villain, and the machinery of the state. In this survival game spanning dimensions, the black-hearted woman and her sharp-tongued System will ultimately tear up the script and reshape the laws of space and time.
